7309 BECBY Bearing Product Overview & Core Advantages
The 7309 BECBY is a single row angular contact ball bearing engineered for applications requiring high precision and the ability to accommodate combined loads. Its 40° contact angle is optimized to support significant axial loads in one direction while simultaneously handling radial loads, making it ideal for machine tool spindles and other high-performance rotational systems. Manufactured to P6 (ABEC-3) tolerance class, this bearing ensures exceptional running accuracy and operational reliability. The brass cage and pre-lubrication contribute to stable performance at its high limiting speed of 9,000 rpm.
